I received my new Chevy a month ago and the only problem that I've found is that its very hard to see the needles on the gauges during the day time. Is there a way I can have the needles changed or painted white. Thanks Rich

Just got my 08 GMC 2500HD... by tacomadude

...after a 2-month wait for it to be ordered from the factory. Got it with the gas 6.0L V8, extended cab, blk/blk, SLE1 with the CD changer, power rear window, towing pkg, and roof top lights. I traded in my Toyota Tacoma for this truck and after being hesitant at first I'm real glad I did. The quality of the 2500 is amazing so far - the interior is well put together with good material use and is VERY comfortable for long drives. The gas V8 has oomph, and in the first tank I averaged 15.7 MPG in about 60/40 split of city/hwy driving. Overall, this is a well oiled machine, and should be great for towing and as a daily commuter. Anyone worried about gas mileage, you'll be pleasantly surprised. The 6-speed auto has great response but is obviously tuned for good mileage. I'm definitely impressed in what GM can do when they put their minds to it.

Idiotic Backup Sensor by caseyjay_48

I have just taken delivery of a Chevy 2007 3500HD Diesel Dually LTZ. So far, I love it. With just 300 miles on it, I get 15 mpg in town and 19 on the hwy. I have noticed a really bad fault with it though, has anyone else found this? The backup ultrasonic sensor system does not give a beeping tone that increases as the distance to an object decreases. Instead, it has three lights on the passenger side of the rear window. Apparently Chevy engineers don’t know that you back up trucks like these by using the side mirrors, not by looking out of the rear window. The tailgate obscures anything behind you. I have almost hit three cars until I found out this they designed it like this. So, you must look behind you to see the backup sensor lights, this means that you can’t use the side mirrors as the same time. If they had just added a beeper to the system, it would allow the driver to back up visually using mirrors and hear the warning sensor at the same time. I am thinking of writing the NTSB to suggest that this is a definite safety hazard that must be corrected.

My backup sensor system only works intermittantly. What you say is totally accurate. It is a very poorly conceived and miserably executed backup warning system.
 
I have to wonder if anyone at GM even had the brains to try this terrible system out before approving it for production. Makes me wonder about a lot more concerning GM's weak ability to design vehicles.

Congratulations on your new truck and sorry your not happy with the Forewarn system, but I think I can help. First off, I would advise reading the 3 or 4 pages in the owners manual regarding the system limitations/options, as it does have the option to turn off the audible alarm which operates through your stereo speakers. In my owners manual this system begins explanation on page 230. It took me about 15 minutes of playing around in my driveway to understand the functionality of the system, I now feel very confident in using it and have utmost confidence in it.

replace that cheap system with one that employs a color camera and monitor. Aftermarket is always better than stock.

Sounds like you have a faulty one...the sensor on mine works just fine...take it to your dealer.

I was able to get 16 mpg on a mostly highway trip in my Denali, but around town I get a lot closer to 10.5 mpg. 11.5 mpg if I baby it. I'm using 87 octane, not the premium fuel...although the fuel door says premium only, everything seems okay with 87 octane. I've read several articles on the Internet that claim using premium fuel is like throwing money away. Any thoughts?

According to ABC news, about 40% of the time you select high test you don't really get high test. Stations routinely run medium or low test through the high test pumps.
Out West, premium is only 91 octane whereas out East, premium is 93 octane. Current vehicles have the ability to adjust their timing to cope with varying octane ratings from a low of 87 to a high of 93+.

If the door say premium, why would you run 87? To save a few bucks?
 
While your knock sensors "should" take care of any knock a good question would be if there ever is some damage due to knock would it be covered under warranty. I'm sure a GM dealer would use it as an opportunity to deny warranty coverage as skytop1 would probably agree.
 
A nickle here and a dime saved there might cost you more in the long run. Course as always the choice is yours.
